Definitions

  • the invention relates to a method for controlling the reed stop in a weaving machine, the reed being set to a desired stop distance.
  • the invention has for its object to provide a method for controlling the reed stop in a weaving machine, in which thick and / or thin points in the fabric are avoided by changing the stop distance of the reed.
  • the procedure in question is used to avoid weaving errors, whereby the course of the procedure depends on whether a weft error, e.g. a weft break, partial weft, etc. or another stop event, e.g. a warp break, deactivates the Loom, etc. is present.
  • a weft error e.g. a weft break, partial weft, etc.
  • another stop event e.g. a warp break, deactivates the Loom, etc.
  • Fig. 1 shows a terry loom.
  • the basic chain 7 runs from a basic warp beam 1 via a tensioning beam 4 to the shed 9.
  • the fabric 10 is drawn off onto a fabric beam 3 via a breast beam 6 and a take-off roller.
  • the pile chain 8 is passed from the pile warp beam 2 to the shed 9 via a pendulum roller 5.
  • a reed 12 of the sley 11 is driven by a main loom drive shaft 13 via a sley control device 14.
  • a servo motor 15 is provided which is drive-connected to the weaving shop control device in order to set the stop distances.
  • the servo motor 15 is electrically connected to a control device 16 in order to control the servo motor 15 in accordance with a control program.
  • the corresponding monitoring devices apply an error signal to the control device 16 which, in a control step by the servo motor 15, sets the shutter control device 14 to a suggested distance VD max , VD max compared to VD target or AD target at least by it is so much larger that the reed and any partial weft that is present no longer changes the position of the previously correctly inserted weft, ie there is a minimal distance to the previously correctly inserted weft.
  • the main shaft of the weaving machine rotates until a stop position is reached, in which a control step "stop initiation" takes place.
  • the main shaft is rotated in the running direction in order to close a predetermined position, for example the end of the field to reach.
  • a control step "shot search" is initiated which, depending on the specialist position, consists of two independent search processes. After the corresponding search process has been completed, the weaving machine is stopped (FIG. 2).
  • the servo motor allows the shed control device to reach the suggested distance VD max either directly after the stop event or before the reed makes the full stop again - Position reached, adjusted.
  • the second control step "stop initiation” follows after reaching the stop position. If an automatic stop is initiated, a control step “machine stop” follows. If subject-specific equality is desired, the subject-specific position is changed in a control step. After the change in the specialist position or in the case of an unequal specialist position, a control step "shot hunting” is initiated. After the weft search process has been completed, the weaving machine is stopped and prepared for the restart once the fault has been rectified (FIG. 3).
  • the characteristic values are stored in the control device 16 (FIG. 1): target proposed distance, target full stop distance, shot density, number of suggested shots up to full stop and tissue type.
  • a correction process can be stored which defines the correction steps. It is pointed out that further characteristic values can be taken into account.
  • correction process is carried out manually, independently of the stored characteristic values can be entered, whereby article peculiarities can be considered.
  • the values of the suggested distance and the full weft distance are corrected.
  • This correction is carried out step by step on the basis of manually adjustable correction steps which are assigned to each stop and are repeated until the desired stop distance for the proposal shot and the full stop shot is reached.
  • the correction can be made within one or more shot groups.
  • the change in length of the stop distance can be the same or different for each group or for each stop.
  • the machine is usually restarted with a manually triggered start command.
  • the weaving machine is brought into a start position. This process is independent of whether terry or smooth fabrics are produced.
  • the shed control device When the machine is restarted, the shed control device is drive-connected to the main shaft of the machine. In order to put the weaving machine from standstill into the operating state, one or more empty shots can be carried out when the weaving machine starts up, VD max being set while the weaving machine starts up and the number of empty shots being freely selectable.
  • the proposal distance VD 1 is set, which is the sum of the target proposal distance VD target plus / minus a correction value Vk 1 is.
  • the first suggestion shot for example in the case of a thin spot in the fabric, is shifted beyond the target suggestion distance, or in the case of a thick spot in the fabric over a distance that is shorter than the target suggestion distance, in the warp direction.
  • the second proposal shot is then entered and the proposal distance VD2 is set, which is the sum of the target stop distance VD target plus / minus a correction value Vk2.
  • the second proposal shot is thus also shifted in the warp direction with respect to the target proposal distance VD target .
  • the stroke distance AD 1 is set, which is the sum of the desired full stroke distance AD desired plus / minus a correction value Ak 1. This shifts the weft group in the warp direction with respect to the target full stop distance AD target . If the correct position of the weft group with respect to the fabric edge is achieved through these correction processes, the further weaving process either takes place without further corrections of the values VD and AD, ie the fabric produced subsequently has a weft density and loop height with the specified values, or with further corrections for at least one additional shot group with changed values for VD and AD compared to the previously fired shot group.
  • the correction values can have the same or different values (FIG. 4).
  • the values VD 1, VD 2 and AD 1 are changed for the next same error event. If a thin or thick spot is found in the tissue, the full stop distance AD is changed, and in the case of a thin spot the value of AD is increased and in the case of a thick spot the value of AD is reduced. If a deviation in the loop height is found, then the values VD1 and VD2 are changed, and that too high Sling the values of VD1 and VD2 are reduced and if the loop is too low, the values of VD1 and VD2 are increased.
  • the weaving machine is usually started with a full weft. Therefore, the procedure is described below based on the rule.
  • a stop distance AD 1 is set, which is the sum of the target full stop distance AD target plus / minus a correction value Ak 1.
  • the weft group is thus shifted accordingly in the warp direction with respect to the target full stop distance AD target .
  • the further weaving process either takes place without further corrections of the values VD and AD, that is to say the fabric produced subsequently has a weft density and loop height with the specified values, or with further corrections for at least one additional shot group with changed values for VD and AD compared to the previously fired shot group.
  • the correction values can have the same or different values (FIG. 4).
  • the value is changed. If a thin or thick spot in the tissue is found, the full stop distance AD is changed, and in the case of a thin spot the value of AD is increased and in the case of a thick spot the value of AD is reduced.
  • the target stop distance is changed in the sense of an extension or shortening in order to include starting points, for example thick and / or thin points Avoid so that fabrics, e.g. terry or smooth fabrics, are produced with a programmed weft density.
